Types of Systems
Conventional Systems
Uses a gravel bed or trench to treat wastewater after it leaves the septic tank. Effluent flows by gravity or pump into the drain field. Best for properties with deep, well-draining soils and no high groundwater or bedrock issues.
Mound Systems
Built when soil conditions prevent a standard in-ground system. A raised sand mound provides proper separation from groundwater or bedrock. Wastewater is pumped evenly through the mound for treatment.
At-Grade Systems
Installed at the natural soil surface without additional sand fill. Ideal for sites that can’t support a conventional system but still meet separation requirements. Effluent is pumped for even distribution.
Aerobic Treatment Units (ATUs)
Adds oxygen to the wastewater treatment process, producing cleaner effluent. Requires less space, making it ideal for small lots or poor soil conditions.
Holding Tanks
Temporarily store wastewater until pumped and transported to a municipal treatment facility. Equipped with an alarm system to notify when the tank is nearly full. Regular pumping is required to prevent overflow.
Private On-Site Wastewater Treatment System (POWTS)
Any private septic system, including conventional, mound, at-grade, or aerobic systems. Must be inspected and maintained regularly according to state regulations.
